Re: [Dev-C++] "C" Numbers and Colors

[Per W. <pw...@ia...>]

To emit your color numbers as integers you have to multiply them with a
constant to increase them from the 0..1 range to span 0.255. Then you
typecast this value to an integer and use %u instead of %f to print them.

When it comes to colors, it all depends on which environment you are in.
If you print to a console supporting ANSI ESC sequences, you can use these
sequences to control the emitted color.

An example is:
printf("\x1b[1m\x1b[32mhello ");
printf("\x1b[32mthere ");
printf("\x1b[35mcolorful ");
printf("\x1b[0mworld\n");

However, the text console in Windows normally don't support the ESC
sequences, resulting in a very ugly printout.

More info about use of ANSI ESC sequences can be found at:
http://www.evergreen.edu/biophysics/technotes/program/ansi_esc.htm

If you are in a graphical environment, then there are normally better
output methods than printf, allowing control not just over color but over
font, printding direction, slanting, ...

Windows have a lot of attribute functions to control the output to the
currently selected DC (Device Context). SetTextColor() and SetBkColor()
are good functions too look a bit closer at :)

Remember that most Windows API have online-browseable documentation
available directly on the Microsoft web site.

[Dev-C++] "C" Numbers and Colors

[Scott <fre...@ve...>]

Newbie C, help...

Is there a way to write the number as 255=20
instead of 0.1 or 0.13434 etc.....

sprintf(str, "R:%1.2f G:%1.2f B:%1.2f", color[0], color[1], color[2]);

And also is it possible to change the text color?

sprintf(str, "Red:%1.2f Green:%1.2f Blue:%1.2f", color[0], color[1], =
color[2]);

I would like have Red (in red), Green in Green, and Blue text....
Is this easy or possible to do in C?

This function is obviosuly part of a 3D plugin, but it uses C commands,
like sprintf....

Cheers,
Scott.

Re: [Dev-C++] compiler error like test.h:2

[Per W. <pw...@ia...>]

All errors are generated by the g++ compiler. However, that is not the
complete message - just part of the information where the error was found,
and how the compiler managed to navigate to the specific file.

There is also the actuall error message, i.e. what was wrong at line 2 of
bank.h.

Hello Blagoja,

I had already set the path in my project. Now I did delete it from there=20
and put it into the compiler options.
The linker finds the library I have set as parameter in the=20
project/options/parameters/linker ( -lwtsApi32  )
I am sure because if I change this name I get the error that the file=20
was not found

Now it continues to tell me that there is a undefined reference
to `WTSEnumerateSessionsA@20' even if the function I use is
WTSEnumerateSessionsA

Does the compiler mangle the names the way that they are different than=20
the icrosoft one ?
Is mangling not used only in c++, my project is c

Re: [Dev-C++] A question about acmDriverAdd and acmDriverRemove APIs

[Gaetano S. <gae...@gm...>]

Hi Alfred,
the only one library used in my project is the "libmsacm32.a", this
library is the only one that contains acmDriverAdd/acmDriverRemove
APIs ("grep docet"), it is in the default library path (dev-cpp/lib)
so no others directories should be included and the linker have the
"-lmsacm32" parameter setted on. Everything seems to be correct, there
are other APIs in the "libmsacm32.a" (such as acmDriverOpen) and I'm
using some of those without any linking problems (but I still need of
acmDriverAdd, without this one the entire project is unuseful).

Re: [Dev-C++] capture command line output

[Alfred P. R. <al...@ya...>]

Hi Noorez,
 
This is a case of redirecting cout (stdout) and/or cerr (stderr) to an input stream.  This is something I've never tried, to be honest.

A simple way would be to output redirect (>) the output of the command line program to a temporary text file, then import and display the text file in your GUI, deleting the text file after capture.
 
BTW: insight.exe probably uses this capability, as it's actually a GUI shell for GDB.  So it's source may be helpful.
